Don't know PSP, but normally this kind of facility would be made
available through an importable module. If that's not an option, check
to see whether PSP allows specifying a script on the command line;
presumably their embedded Python permits you to exit PSP.

This is Python. We don't care much about theory, except where it intersects

Yes. Do a find for 'JascApp.pyd'. Or just for '*.pyd'.

Yes, <something> == 'pyd' usually. But you never know the ways people
(and especially large companies) like to mess about with conventional
ways of doing things.
The way module search paths are handled is generally less easy to
predict. Even in the normal case, I can't remember how .pyd's are
found, if I ever knew. Presumably Python is bundled with the
application, in some form? In which case, it may not be trivial to
import the module. Probably not hard once you know the answer, though
<wink>.

Marc,
This is not an answer to your question... but if you just want to convert an
image file into another format then upload it to a server you could use a
pure python solution (well pure python + PIL)
PIL is here:-
http://www.pythonware.com/products/pil/
In fact a quick browse through the handbook and I found this:-
http://www.pythonware.com/library/pil/handbook/pilconvert.htm
and I quote:-
"""
Convert an image from one format to another. The output format is determined
by the target extension, unless explicitly specified with the -c option.
$ pilconvert lena.tif lena.png
$ pilconvert -c JPEG lena.tif lena.tmp
"""
To upload the image to a server you could use the ftplib module...

Marc,
Point taken... I just can't resist showing you how easy it is in Python.....
# PIL IMPORTS
import Image, ImageEnhance
im = Image.open("gnome-mixer.jpg")
enhancer = ImageEnhance.Sharpness(im)
eim = enhancer.enhance(2.0)
eim.save("gnome-mixer-sharp.jpg", "JPEG")
eim.thumbnail((10, 10))
eim.save("gnome-mixer-thumb.jpg", "JPEG")
And this is the first time I've used PIL.
Cheers,
Martin.

The fact that it's embedded doesn't necessarily mean that you can't
import it from outside the running application, but it may well not be
possible. Worth a try, though.
As I said in an email, don't forget COM -- maybe one of those .py
files you have is just a wrapper around a COM automation interface.
The "Python for Windows extensions" (aka win32all) is what you need
for most COM stuff.

Have you tried running a script from the commandline?

I just downloaded the PSP8 evaluation. It installs with a bunch of sample
scripts. These sample scripts all have a file extension .PspScript, and the
file association set up by the installer associates .PspScript with the
command: "...\Paint Shop Pro.exe" "/Script" "%1"
Unfortunately whenever I start Paintshop pro it gives me a popup window
telling me its an evaluation copy and requiring me to confirm the window
before it proceeds. When started with a script that uses a dialog there
appears to be a deadlock as the script cannot proceed with this window
displayed, and the window won't accept any input. It works alright though
for scripts that don't try to do anything interactive, and I would guess
that a properly registered copy of the program would run scripts with
dialogs correctly, but you are probably in a better situation to determine
that than anyone on this newsgroup.

The documentation is available as a separate download (for those people who
didn't get their copy on CD, such as the evaluation copy). 4798 files, but
having looked at them I wouldn't say they were the best documentation ever.

Very wise. It would take you a whole afternoon to learn Python well
enough to do what you want with PIL <0.2 wink>.
http://effbot.org/zone/pil-imageenhance.htm
http://effbot.org/zone/pil-imagefilter.htm
And I'm sure that afternoon will pay off again.
OK, and another day to get out of the mess your OS (whichever one you
use) will try to get you into with naming conventions, filesystem
paths and other plumbing <0.8 wink>.

I don't know whether that is doable with the python scripting in
PaintShop Pro as I haven't got round to upgrading yet, but I do know
that Python+PIL can do that in very few lines of work. With some
tweaking, you can use py2exe to make your script into an executable,
thereby removing the need for every user to install python.

That's a very sound argument. However, if you are planning on doing any
image processing in the future, you will never regret the time spent
learning Python and PIL. In fact, it is a fairly good possibility that
you would look back and wonder how you ever survived without it.

Excellent! You have much less to _un_learn then. :-)

Thanks for mentioning PSP 8's support of Python. I have an older copy
that I haven't updated for a while, and this scripting capability is an
update worthwhile making!

I just DL'd an eval copy also, and a couple of thoughts.
1) Duncan's already pointed out the file association, so it looks like
that's an easy way to ensure that the Python script is handled properly
by PSP.
2) Python was installed there for me. You should see "python22.dll" in
your [C:\Program Files\Jasc Software Inc\Paint Shop Pro 8] (or
appropriate) directory. There shold also be a [\Python Libraries]
subdirectory with other required files.
3) Interestingly, I can't find any sign of a JascApp.* file anywhere. I
would expect to see a PYC or PYD given the Import command, but being a
relative newbie myself, don't have a good understanding of how this
could be. But, hey - it seems to work, so I won't complain.
4) I would expect that for btach processing you would also pass the file
to process at the command shell, but they do seem to offer some extra
help for batch processing (the "Processing all the files in a directory"
section on page 26 of the script.pdf manual (available at their website
if you've only got all the HTML documentation from the CD) I agree that
the Docs could be a bit more helpful!
5) Of course the messages showing off PIL have opened my eyes to how
easy it is to use that - and Python is LOTS easier than Perl IMHO.

Sorry, I must have misinterpreted your use of the word "convert" then. ;-)

This would work if they "embedded" Python rather than "extending" it.
Using Python as an embedded scripting engine, the embedding
application (probably the main PSP executable) can define whatever
modules it wants as built-in modules prior to executing Python code.
The "modules" actually exist right in the executable that is starting
the Python interpreter.
If true, then it would make it less likely you could use that
functionality from an externally initiated Python script, since that
script wouldn't have started from the right environment containing
those built-in modules.

sys.argv
For fancier options, check out optparse (new in 2.3) or getopt.

Greg,
If you do upgrade, please let them know that the python scripting was
a major factor in your decision to do so.

Marc,
Looks like there could be (at least) two ways to do it...
The ImageDraw class allows you to draw onto an existing image like so:-
im = Image.open("gnome-mixer.jpg")
draw = ImageDraw.Draw(im)
draw.text((5, 5), "SOLD", fill="black")
I have not investigated how (and if) you can rotate the text - I know you can
change it's font etc...
The second way would be to paste a SOLD image onto the original image
im = Image.open("gnome-mixer.jpg")
im.paste(Image.open("sold.jpg"), (5, 5))

How about this:
from PIL import Image, ImageFont, ImageDraw, ImageChops
im = Image.open("test.jpg")
im.thumbnail((128, 128), Image.ANTIALIAS)
font = ImageFont.truetype("arial.ttf", 30)
def AddOverlay(im, origin, text, angle=-45):
# Create an overlay with white text and subtract it from the image.
# This effectively blacks out the area to be overlaid.
overlay = Image.new(im.mode, im.size)
draw = ImageDraw.Draw(overlay)
draw.text(origin, text, (255, 255, 255), font=font)
overlay = overlay.rotate(angle)
stamped = ImageChops.subtract(im, overlay, 1, 0)
# Now create a red overlay and add it to the subtracted image
overlay = Image.new(im.mode, im.size)
draw = ImageDraw.Draw(overlay)
draw.text(origin, text, (255, 0, 0), font=font)
overlay = overlay.rotate(angle)
stamped = ImageChops.add(stamped, overlay, 1, 0)
return stamped
stamped = AddOverlay(im, (10, 50), "SOLD!")
stamped.show()
